There is a shallow ditch in the middle of the chin, which is called the beauty ditch. The length of the ditch varies from person to person. Some are longer, others are shorter and look like pits. This is also called "European chin". In fact, everyone has it, but to varying degrees, it is not shown. You can feel a seam in the middle by touching the chin bone with your hand. Few people in the east have a beauty gap because of physical reasons, while there are more people in Europe and America.

The beauty ditch is like a beauty mole for an individual. It's natural, and you can also have surgery, but it should be based on your face shape, otherwise the uglier the better. It is also every flower that enters its own eyes. Some people look good, others don't.

According to the data, only 20% of European and American stars have a beauty gap, while in Asia, there are very few people with this kind of chin, so there are very few stars with ω-shaped chin, that is, the beauty gap.
